About the Job

Requirements

  • A Master of Science degree in Data Science, Statistics, Computer Science, or a similar quantitative field.
  • At least five years of practical experience writing algorithms in machine learning, statistical modeling, neural networks, and pattern recognition from data exploration.
  • Five years of experience in data science or machine learning.
  • Strong programming skills in Python.
  • Proven experience with time-series analysis and anomaly detection.
  • Proven experience with statistical modeling and machine learning algorithms.
  • Hands-on experience with root cause analysis or fault tree analysis and failure modeling.
  • Experience working with real-world, noisy, and large-scale datasets.
  • Experience with agentic artificial intelligence or large language model systems, including tool-calling architecture, retrieval-augmented generation pipelines, and prompt engineering and evaluation frameworks.
  • Familiarity with distributed systems and scalable machine learning infrastructure.
  • Familiarity with MLOps practices, including continuous integration and delivery, monitoring, and model versioning.
  • Knowledge of signal processing or physics-based modeling.
  • Knowledge of graph-based reasoning or causal inference.
  • Full software development lifecycle experience and comfort working with Agile and iterative methodologies.
  • Experience with test-driven development and tools to identify performance issues and memory leaks.
  • Ability to investigate and apply new technologies.
  • General technical knowledge of semiconductor metrology equipment.
  • Strong engineering analytical and problem-solving skills.
  • Ability to prioritize multiple tasks and work longer than normal hours as needed during releases and customer escalations.

Responsibilities

  • Develop and maintain artificial intelligence software and systems for company products.
  • Develop algorithms in machine learning, statistical modeling, neural networks, and pattern recognition using data exploration.
  • Develop, train, and deploy machine learning models for time-series forecasting and anomaly detection, as well as classification and regression on tabular and sensor data, predictive maintenance, and failure prediction.
  • Design end-to-end machine learning pipelines covering data ingestion, feature engineering, model training, evaluation, and deployment.
  • Lead and support root cause analysis investigations using data-driven approaches.
  • Build frameworks for fault tree analysis and failure mode identification.
  • Collaborate with engineering and operations domain experts to translate failure patterns into machine learning features and models.
  • Design and develop agentic artificial intelligence systems for autonomous reasoning over structured and unstructured data, tool usage, and multi-step decision-making and diagnostic workflows.
  • Implement large language model systems with tool-calling frameworks, retrieval-augmented generation, and structured outputs and validation pipelines.
  • Partner with data engineers, software engineers, and domain experts.
  • Build scalable, production-ready solutions using Python machine learning frameworks such as TensorFlow, PyTorch, and scikit-learn; data processing tools such as pandas, Spark, and SQL; REST APIs such as FastAPI and Flask; and containerization tools such as Docker and Kubernetes.
  • Deploy models and services using REST APIs and containerization.
  • Work with time-series databases such as Prometheus and InfluxDB; analytical databases such as ClickHouse and PostgreSQL; and vector databases such as Qdrant and FAISS.
  • Translate business problems into technical solutions.
  • Create architecture and complex designs independently and document them.
  • Integrate and test software to confirm compliance with specifications.
  • Develop functional specifications.
  • Participate in design reviews, peer code reviews, and test reviews.
  • Perform functional tests.
  • Travel internationally for business purposes up to 5%.
